std::string mrpt::math::MATLAB_plotCovariance2D(const CMatrixFloat &cov22, const CVectorFloat &mean, float stdCount, const std::string &style = std::string("b"), size_t nEllipsePoints = 30)

Generates a string with the MATLAB commands required to plot an confidence interval (ellipse) for a 2D Gaussian (‘float’ version)..

Parameters:

• cov22 – The 2x2 covariance matrix

• mean – The 2-length vector with the mean

• stdCount – How many “quantiles” to get into the area of the ellipse: 2: 95%, 3:99.97%,…

• style – A matlab style string, for colors, line styles,…

• nEllipsePoints – The number of points in the ellipse to generate
